Let me give you a little longer answer. Right now we have this TODO
item:
* Allow backslash handling in quoted strings to be disabled for
portability
The use of C-style backslashes (.e.g. \n, \r) in quoted strings is not
SQL-spec compliant, so allow such handling to be disabled. However,
disabling backslashes could break many third-party applications and
tools.
Now, if we don't address it, we might as well remove the TODO item and
say we are never going to change it, because right now, we have a plan,
and I think the longer we go the harder it will be. And if we don't
change it, it makes it quite hard for people to port applications to
PostgreSQL. Fundamental queries like:
SELECT * FROM files WHERE filename = 'C:\tmp'
do not work. When a query with a single table and single WHERE clause
isn't portable, it seems like a problem. If this was isolated to CREATE
TABLE or something, it wouldn't be a big deal.
One possible idea is to have the warning in 8.1 configurable, so you can
turn it off, and see how well things go in the community. At a minimum,
the warning will flag non-portable queries to help in porting, and folks
can use E'' for non-porable string representations.
